of september. here is what they're seeing. president obama's campaign outspending mitt romney's campaign almost 2-1 in the last three weeks of september. take a look at the next level. super pac level, republican super pacs outspending 2-1. in some senate races it shows more than 50% of the ads on air in swing states are coming from these super pacs. fascinating measure just how much they're having an effect and, in some cases, propping up campaigns. >> the two biggest super pacs out there, dedicated to president obama and romney, they're obviously the chief of each of those is about to come on the show. how are they doing specifically? >> in terms of money raised to debt, current year-to-date totals we have, the general ratio shows restore our future, romney associated super pac outspending the super pac associated with president obama. for the month of august, first time liberal super pacs outraised conservative super pacs. the restore our future super pac aired no ads from a period of august 21st to september 19th. they were dark. that's an extraordinary thing and raises a lot of questions.
